Wulf, I'm thinking about adding the red to the nut to the left. Theory is that he took it off that bundle so that if I threw the switch I would trip the gfi and take out all the outlets on the patio every time. Maybe I'm nuts. What do you think?

Also, if this works and the light comes on the next step is to install back in the niche. I would do that with the power off just to be safe. Then power back on, turn on the light. How the hell do I make sure the water isn't electrified ? Or would the gfi pop if there was water present in the circuit?
